NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

The geometrical efficiency equation for a proton recoil telescope exposed to a monoenergetic point neutron source is solved by a power series expansion that permits simple and accurate reduction of raw telescope data to absolute neutron fluxes or source strengths. Two parameters are allotted for description of source anisotropy and three parameters are allotted for description of hydrogen scattering anisotropy in the center-of-mass system. The relativistic transformation of the hydrogen differential scattering cross section from center-of-mass to laboratory system is used.
